Thermospheric response to a magnetic substorm
Arthur D. Richmond,S. Matsushita +1 more
TL;DR: In this article, a computer model is used to simulate the winds and temperature variations in the thermosphere which result from auroral region electric currents during a large isolated magnetic substorm.
Journal ArticleDOI
Interplanetary magnetic field control of high-latitude electric fields and currents determined from Greenland Magnetometer Data
TL;DR: In this article, an empirical model of high-latitude magnetic perturbations, parameterized in terms of the By and Bz components of the interplanetary magnetic field (IMF), was derived from 20-min average magnetometer data observed during summer at the chain on the west coast of Greenland and the corresponding IMF information from the HEOS 2 satellite.
Journal ArticleDOI
On the production mechanism of electric currents and fields in the ionosphere
TL;DR: In this paper, the dynamo theory of Sq variations is reexamined to see if it can be reconciled with recent observations of ionospheric winds and electric fields.
Journal ArticleDOI
Interactions Between the Ionosphere and the Magnetosphere for Sq and L Variations
TL;DR: In this article, the results of mapping these dynamo-region electrostatic fields into the magnetosphere are briefly presented, together with the earth's main magnetic field, producing drift motions of magnetospheric plasma particles.
